1. A system comprising:
a ground station with a ground winch and cable unit, the ground winch and cable unit includes a ground spool for accommodating a tether cable;
an unmanned robot comprising
a robotic controller module configured to control operations of the unmanned robot, and
a winch and cable unit mounted on the unmanned robot, the winch and cable unit includes a spool for accommodating the tether cable;
wherein the tether cable comprises
a first end connected to the spool of the winch and cable unit,
a second end connected to the ground spool of the ground winch and cable unit, and
wherein the tether cable comprises first and second extendable ends the first extendable end is extended by releasing the tether cable from the spool during operation, and the second extendable end is extended by releasing the teacher cable from the ground spool during operation; and
wherein the ground winch and ground cable unit is configured to maneuver the ground station by controlling retraction of the tether cable from the ground spool of the ground winch and cable unit.
